Failed Marine Battery Charger - Runaway Voltage

[@audentesfortunailuvat]

I don't know why this channel isn't at the top of all Marine electrical searches. Great information. I am setting up a solar/wind generating circuit on a boat moored and may need to rethink the whole 'unattended' aspect. Good stuff.

Thank you. I have the same unit from 1979 on a used sailboat I purchased. I will be aware.

Great informative video. I believe I'm having the same issue. I have a dual 15 amp. One battery reading good on charger. Other was at 10 %. So I switched the wires on the batteries. Just to see if it was actually the charger & not the NEW batteries. And now it's reading 30% on the #2 battery. Where as number 1 battery was at 10%. Any ideas as to why the difference in % ? All batteries had the same voltage 12.7 volts.

If you ran the charger through a acr would that prevent this? Thank you
